Description

Technical Field

[0001] This utility model relates to the field of battery structure technology, specifically a battery structure with active thermal regulation function. Background Technology

[0002] With the rapid development of new energy technologies, energy storage systems and portable electronic devices, batteries, as core energy supply components, directly determine the reliability of end products through their performance and lifespan. Currently, high-capacity and high-power-density batteries have become the mainstream choice. However, these batteries continuously generate heat during charging and discharging, so it is necessary to regulate the temperature of the battery through battery structure. However, existing battery structures with active temperature regulation functions still have certain defects in use. As proposed in application number CN202223152299.1, an integrated thermal management battery module includes a battery casing. Multiple coplanarly arranged water-cooled plates are disposed inside the battery casing, with the battery located between the water-cooled plates. A liquid thermal PTC is fixedly connected to one end of the inner side of the battery casing, and water pipes are fixedly connected to both ends of the liquid thermal PTC. By utilizing the multiple water-cooled plates surrounding the battery within the battery casing and the connection of the water pipes to divert external water cooling, the battery achieves both water cooling and heat transfer insulation effects, thus ensuring the battery's thermal stability. When operating in different external temperature environments, the liquid thermal PTC can be used to regulate the temperature. In actual use, the core of the temperature control of this solution relies on "liquid thermal PTC + external water cooling source". However, according to the publicly available information, it only clarifies the heating regulation function of the liquid thermal PTC and does not mention any active cooling components. When the battery is in a high-temperature environment, it can only rely on the passive cooling of the external water cooling source. If the temperature of the water cooling source itself rises due to environmental influences or the heat load exceeds the cooling capacity, it will not be able to achieve effective cooling and can only passively withstand the temperature rise, which may easily trigger the risk of battery thermal runaway.

[0003] Therefore, we propose a battery structure with active thermal regulation to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a battery structure with active cooling and heating regulation function to solve the problem in the background art where the lack of active cooling components makes the passive cooling method of external water cooling source in high-temperature environments susceptible to its own temperature rise or heat load overload, thus failing to achieve effective cooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery structure with active thermal regulation function, including a battery mounting box and a processor, wherein a connecting seat is fixedly installed at the front end of the battery mounting box, and a thermal regulation mechanism is installed inside the battery mounting box and on the front side of the connecting seat for thermal regulation of the battery, and the thermal regulation mechanism is connected to the processor. The front end of the connector is fixedly installed with a positioning shell by screws, and the upper and lower ends of the positioning shell are provided with heat dissipation grooves at equal intervals. An active heat dissipation mechanism is fitted inside the positioning shell to dissipate heat from the temperature control mechanism.

[0006] Preferably, the heating and cooling control mechanism includes liquid cooling pipes symmetrically fitted and installed inside the battery mounting box. The inlet and outlet ends of the liquid cooling pipes are connected through a connecting seat. A refrigeration box is fixedly installed on the front side of the connecting seat. The outlet end of the liquid cooling pipe is connected to the right end of the refrigeration box. A pump is fixedly connected to the inlet end of the liquid cooling pipe. The pump is fixedly connected to the left side of the refrigeration box via a bracket. An outlet pipe is fixedly connected to the inlet end of the pump. The outlet pipe is connected to the left end of the refrigeration box.

[0007] The above-mentioned structural design, with the liquid cooling pipe in contact with the battery mounting box and the internal battery, and the pump driving the coolant to circulate between the liquid cooling pipe and the cooling box, can efficiently dissipate the heat generated by the battery during operation, achieve uniform cooling of the battery, increase the heat dissipation area and heat dissipation efficiency, and meet the heat dissipation requirements of the battery under high load operation.

[0008] Preferably, the heating and cooling control mechanism further includes a semiconductor cooling plate fitted and installed at the front end of the cooling box, wherein heat dissipation fins are fitted and installed on the front side of the semiconductor cooling plate, and temperature sensing elements are embedded and installed at equal intervals on the left side of the battery mounting box.

[0009] With the above-mentioned structure, the semiconductor cooling plate can achieve active cooling through electrical energy, providing a continuous cold source for the coolant in the cooling box and enhancing the cooling effect. The heat dissipation fins can increase the heat dissipation area of ​​the semiconductor cooling plate, accelerate its own heat dissipation, and ensure stable cooling efficiency. The temperature sensing element can monitor the battery temperature in the battery mounting box in real time, providing accurate temperature data support for heat and cold control, and realizing dynamic sensing and targeted control of battery temperature.

[0010] Preferably, the extraction pump, the semiconductor cooling plate, and the temperature sensing element are connected to the processor.

[0011] With the above-described structure, the processor can receive temperature signals transmitted by the temperature sensing element and automatically control the start, stop, and speed of the pump, as well as the working power of the semiconductor cooling plate, according to the preset temperature threshold. This enables intelligent and automated temperature control, improves the response speed of temperature control, avoids manual intervention, reduces unnecessary energy consumption, and extends the service life of the equipment.

[0012] Preferably, the active heat dissipation mechanism includes a mounting frame symmetrically fitted and installed at the front end of the positioning shell, a support plate is installed at an equal angle on the inner rear end of the mounting frame, a drive motor is fixedly installed on the inner end of the support plate, a cooling fan blade assembly is connected to the shaft end of the drive motor, and a filter screen is installed on the support plate.

[0013] With the above-mentioned structure, the drive motor drives the cooling fan blades to rotate at high speed, which can accelerate the airflow inside the positioning shell, enhance the heat exchange efficiency between the heat dissipation fins and the outside air, and further improve the heat dissipation effect of the semiconductor cooling plate. The filter screen can effectively block external dust and impurities from entering the positioning shell and internal mechanism, avoiding dust accumulation that may affect heat dissipation performance or cause component damage.

[0014] Preferably, the active cooling mechanism further includes a transmission rod fixedly installed at the rear end of the cooling fan blade assembly. The transmission rod is connected through the semiconductor cooling plate and the cooling fins. A sealed bearing is installed at the penetration point between the transmission rod and the connecting seat. A stirring blade is symmetrically sleeved on the outer ring of the transmission rod located inside the cooling box. The stirring blade can mix the coolant inside the cooling box.

[0015] With the above-mentioned design, when the transmission rod rotates synchronously with the cooling fan blade assembly, it can drive the stirring blade to stir the coolant in the refrigeration box, so that the coolant is heated and cooled evenly, avoiding localized excessively high or low coolant temperatures in the refrigeration box, and improving the temperature control efficiency of the refrigeration box for the coolant. At the same time, this transmission structure integrates the active heat dissipation mechanism with the coolant stirring function in the refrigeration box, eliminating the need for additional drive components, simplifying the overall structure, and reducing the size and energy consumption of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a battery structure with active thermal regulation function, including a battery mounting box 1 and a processor 9. A connecting seat 2 is fixedly installed at the front end of the battery mounting box 1. A thermal regulation mechanism for regulating the temperature of the battery is installed inside the battery mounting box 1 and on the front side of the connecting seat 2. The thermal regulation mechanism is connected to the processor 9. The thermal regulation mechanism includes liquid cooling pipes 3 symmetrically fitted inside the battery mounting box 1. The inlet and outlet ends of the liquid cooling pipes 3 are connected through the connecting seat 2. A cooling box 4 is fixedly installed on the front side of the connecting seat 2. The liquid outlet end is connected to the right end of the refrigeration box 4. The liquid inlet end of the liquid cooling pipe 3 is fixedly connected to the extraction pump 5. The extraction pump 5 is fixedly connected to the left side of the refrigeration box 4 through the bracket. The liquid outlet end of the extraction pump 5 is fixedly connected to the liquid outlet pipe 6. The liquid outlet pipe 6 is connected to the left end of the refrigeration box 4. The cooling and heating control mechanism also includes a semiconductor cooling plate 7 embedded in the front end of the refrigeration box 4. Heat dissipation fins 8 are attached to the front side of the semiconductor cooling plate 7. Temperature sensing elements 19 are embedded at equal intervals on the left side of the battery mounting box 1. The extraction pump 5, the semiconductor cooling plate 7, and the temperature sensing elements 19 are connected to the processor 9. In the above-described structure, the battery structure with active thermal regulation function first monitors the working temperature of the battery inside the battery box in real time by temperature sensing elements 19 embedded at equal intervals on the left side of the battery mounting box 1, and continuously transmits the temperature data to the processor 9. After receiving the temperature signal, if the processor 9 determines that the battery temperature exceeds the preset safety threshold, it will activate the thermal regulation mechanism to actively cool down. At this time, the extraction pump 5 connected to the processor 9 starts to work, and extracts coolant from the cooling box 4 through the liquid outlet pipe 6 and delivers it to the symmetrical liquid cooling pipe 3 embedded inside the battery mounting box 1. The liquid cooling pipe 3 is in direct contact with the battery and efficiently absorbs the heat generated by the battery. The coolant carrying heat then flows back to the cooling box 4 along the liquid cooling pipe 3. At the same time, the processor 9 controls the start of the semiconductor cooling plate 7 embedded in the front end of the cooling box 4. The heat dissipation fins 8 attached to the front side of the semiconductor cooling plate 7 accelerate the dissipation of heat from the semiconductor cooling plate 7 itself, ensuring that it continuously and stably cools the coolant in the cooling box 4, so that the coolant returns to a low temperature state and participates in the circulation again. Throughout the process, the processor 9 will dynamically adjust the speed of the pump 5 and the working power of the semiconductor cooling plate 7 according to the real-time temperature feedback from the temperature sensing element 19, so as to realize the active regulation of the battery temperature and ensure that the battery is always in a suitable operating temperature range.

[0021] The front end of the connecting seat 2 is fixedly installed with a positioning shell 10 by screws. The upper and lower ends of the positioning shell 10 are provided with heat dissipation grooves 11 at equal intervals. An active heat dissipation mechanism is fitted inside the positioning shell 10 for heat dissipation of the heat regulation mechanism. The active heat dissipation mechanism includes a mounting frame 12 symmetrically fitted at the front end of the positioning shell 10. A support plate 13 is installed at equal angles on the inner ring of the rear end of the mounting frame 12. A drive motor 14 is fixedly installed on the inner end of the support plate 13. A heat dissipation fan blade assembly 15 is connected to the shaft end of the drive motor 14. A filter screen 16 is installed on the support plate 13. In the above-mentioned structure design, during the active heat dissipation process of the battery structure, the positioning shell 10 is first fixed to the front end of the connecting seat 2 by screws. The heat dissipation grooves 11 opened at equal intervals at the upper and lower ends provide channels for airflow circulation. The active heat dissipation mechanism embedded in the positioning shell 10 starts working around the heat dissipation requirements of the heat regulation mechanism. The core power of the active heat dissipation mechanism comes from the drive motor 14 in the inner ring of the rear end of the mounting frame 12. The mounting frame 12 is symmetrically fitted into the front end of the positioning shell 10. The drive motor 14 is stably fixed by the support plates 13 distributed at equal angles. When the drive motor 14 is powered on and started, its shaft end will drive the heat dissipation fan blade assembly 15 to rotate at high speed, forming a directional airflow. This airflow directly acts on the heat dissipation fins 8 in the heat regulation mechanism, accelerating the heat exchange on the surface of the heat dissipation fins 8, helping the semiconductor cooling plate 7 to quickly dissipate the heat generated during its operation, and preventing the semiconductor cooling plate 7 from experiencing a decrease in cooling efficiency due to heat accumulation. Meanwhile, the filter screen 16 installed on the support plate 13 filters the airflow entering the positioning shell 10, preventing external dust and impurities from adhering to the heat dissipation fins 8 or the surface of the drive motor 14. The heat dissipation slots 11 of the positioning shell 10 serve as airflow channels, allowing the airflow carrying heat to be discharged smoothly, ultimately achieving efficient auxiliary heat dissipation for the heat regulation mechanism and ensuring stable temperature control performance.

[0022] Example 2: Based on Example 1, this utility model adopts the following... Figure 6 The technical solution shown further discloses that the active heat dissipation mechanism also includes a transmission rod 17 fixedly installed at the rear end of the heat dissipation fan blade assembly 15. The transmission rod 17 is connected through the semiconductor cooling plate 7 and the heat dissipation fins 8. A sealed bearing is installed at the through point of the transmission rod 17 and the connecting seat 2. The transmission rod 17 located inside the cooling box 4 is symmetrically fitted with stirring blades 18 on its outer ring. The stirring blades 18 can mix the coolant inside the cooling box 4. The above structure design adds a transmission linkage structure to the active heat dissipation mechanism based on the first embodiment. Its working principle needs to be combined with the linkage logic of the original heat dissipation components and the new components. When the drive motor 14 starts and drives the heat dissipation fan blade group 15 to rotate at high speed to assist heat dissipation of the heat dissipation fins 8, the transmission rod 17, which is fixedly connected to the rear end of the heat dissipation fan blade group 15, will rotate synchronously with the fan blades. The transmission rod 17 passes through the semiconductor cooling plate 7 and the heat dissipation fins 8 in sequence, and is sealed at the penetration point with the connecting seat 2 by a sealing bearing. This ensures the stability of the transmission rod 17 when rotating and effectively prevents the coolant inside the cooling box 4 from leaking from the penetration gap. When the part of the transmission rod 17 extending into the interior of the refrigeration box 4 rotates, the stirring blades 18 symmetrically mounted on its outer ring will rotate synchronously, continuously stirring the coolant in the refrigeration box 4, breaking the temperature gradient formed by the coolant being close to the semiconductor cooling plate 7, avoiding the situation of "local overcooling and remote overheating", and keeping the temperature of all coolant in the refrigeration box 4 uniform.
